SPECIFICATION forming part of Letters Patent Nb. '7l-73915, datedJanuary 6, 1903.

Application'ied August 18,19Z.

Serial No. 120,015 CNO model.)

Be itirnown that I, HERBERT E. PENNEY, a citizen of `the United States,residing at Minneapolis, county of.Hennepin, and State of Minnesota,have invented certain new and useful Improvements in Steam-Generators,of vwhich the following is a specification;

My invention relates to vertical steamfgenerators of the sectionalwater-tube type.

The object of the invention is to dispense with the usual water-legformed between ver, tical shells and to substitute therefor a water-drumcomposed ofconimunicating horizontal headers and upright return-pipes incircular arrangement and connected with headers or a steam-ring aboveandto provide in the interior aseriesof verticalseparatelyremovablemanifolds or tube-sections composed oi' headers and inclined tubes.

My improvements are illustrated in the accompanying drawings, in which-Figure 1 is avert-ical .sectional view of a steam-generator embodying myl improvements. Fig. 2 is a horizontal section of the same on theirregular line w w of Fig. 1. Fig. 3 is a top or plan view of Fig. 1with the` hood and chimney removed, and Figs. 4 and 5 are enlargeddetail views of the upper and lower headers and their connections. Inthe drawings, 1 designates a cylindrical 3, the hood over the top of thegenerator; 4, the flragrate, (shown in broken lines,) and 5 the re door.These features may be of any usual or suitable construction. In thelower portion of the shell is a series of horizontal circle by shortcoupling-pipes 7, to provide the water-space or water-drum ofthegenerato'r. Supply-pipes are connected to the water-drum at anydesired points. To the top of the headers 6 of the watendrum iisconnected a series of vertical pipes 9, that connect withthe undersideof a series of upper headers 10, which may correspond in form andarrangement with the lower headers 6 and may be similarly connectedtogether to form a Vsteam-ring,r or may be independent of one another.

In using the term steam-ring herein I rangements. The pipes 9 are forthe return of water from the steam-ring to the 1.vaterlevel below. Thesepipes may be placed as close together as desired to prevent the escapeof any great amount of heat from the` combustion-chamber within theircircle. l

Within the circle of the return-pipes is a series of manifolds ortube-sections arranged in parallel vertical planes, and cachtube-section consists of a pair of opposite verticai headers 11 andinclined connecting-tubesm, the tubes of each section preferablyinelining in opposite direction from those of adjoining sections. Theheaders shown in the drawings are made up of a pluralitvo short sectionsplaced end to end and united by removable ppe-couplings 13.

,of the headers are provided with tapped in clined sockets 14, arrangedin staggering or der, to receive the threaded ends of the water-tubesl2.The lower ends'of the headers are connected by detachable pipe-couplings15 with the water-drum and their upper ends are detachably connected bynent-pipe connections 1G, arrangedto discharge downward into the'steamlring. The pipe connections i5 and 16 may be of any usual orsuitable construction adapted to he conveniently disconnected to perdaitthe removal of a tubesection. 1 A steam-drum 17 of any desirable form(shown as a short upright cylinder .in the drawings) is arrangedcentrally over the se ries of tube-sections. The headers 10 of thesteam-ring are connected with the lower por tions of this drum by pipes18, and a stean1- discharge pipe i9 is connected to its upper portion.

By disconnecting the tube-section connections 15 and 16 with thewater-drum and steam-ring the selected' tube-section can be readilyremoved, and by also disconnecting a selected water-drum and steam-ringsection from adjoining sections such section, including itslreturn-pipes, can be readilyT removed. Y

In operation water is supplied from the water-druu1 to the lower headersof the tubesect-ions, and when steam is generated it rises through thetubes and headers and, together with whatever water it may carry over,discharges downward into the steam-ring, 'and The inner surfaces.

ICG

l einem the nteem passes ofi?" through the pipes 18 to 'tineesteem-drum, While the Weterdeecends directly through the pipes J towardthe Weterairnm to the Water-,level of the generator.

Having described my invention, what claim, and desire to secure byLetters Patent, 1sv i. In a steazngenerntor, the combination with eninclosing shell, a. water-drum composed of segmental sections, asteam-ring composed of corresponding sections, end e, series ofretnrnlpipes connecting said drum and ring sections; of a. series ofinterior tuben sections comprising opposite vertical headers and tubesconnecting them, detachable connections leading` from the Water-drum tothe lower ends of the headers, .and detachable pipe connections lendingfrom the upper ends of the headers and discharging downward intothesteam-ring,snbsta.ntially ne eet forth.

2. In e eteamgenerator, the combination with an inclosing shell, ewater-drinn coniposed of segmentalsections, e. steeinwingr composed ot'corresponding eectione, and e. seriesoi return-pipes connecting sciddrum end ring sections; ol a series of interior sep retely-removabletube-sections arranged vin parallel vertical plenos, each inbe-eectioncomprising vertice-l headers and connectingtnhee, detachable connectionsleading from the .veter-drinn to the lower ende of the heed.- ere, anddetachable pipe connections leading from the npperiende of the headersand discharging downward into the steam-ring, substentially as setforth.

3. in e steam-generator, the combination with en inclosin-g sh ell, awater-drn m,a steam trom' the upper ends of the headers and dischargingdownward into the steam-ring, enh

stantieliy as eet'forth.

4. Inl n. steam-generator, the combination with an inclosingehell, ewaterdrum,asteani ring, sind e series of return-pipes connecting euchdrnm and ring; of aseres of seperatelyreinovehle tube-sections, eachtnbefsection comprising opposite vertical headers and in' clined tubesconnecting them, the inclinations of the tniiee being opposite inadjacent tube-sections detachable connections lending fromthewzttendrnin to the lower ends of the heeders, and detachable pipeconnections lending from the upper ends of the vheaders end dischargingdownward into the steemring, snietantiel'ly as set forth.

in testimony whereof l have signed my neme to this specification, in thepresence of two subscribing witnesses, this 7th day of Angnst, 1902.
